7. Instructions
< Broadcast mode (Mode 4) >
When the instruction input comes ON with the operand B+1 is 4, the Broadcast mode (mode 4)
is selected. In this mode, the T1-16S sends the user specified Write command to all the
Inverters as broadcast.
This mode is useful to send Run/Stop command to all the Inverter at the same time.
Sends the specified command with comm and data to all Inverters (broadcast)
Checks the acknowledge from #0 Inverter
The Inverter number specified by the operand B is ignored.
The scan execution status and the Inverter communication status are stored in the operand
B+2 to B+7. (only #0 Inverter responds)
The command code and the command data setting registers are indirectly specified by the
operand A and A+1.
When the instruction input is reset to OFF, the operation is stopped after receiving the
response from the Inverter.
Example
Data table designation Parameter & status RS-485 port
D1000 4 RW200 (any 0 to 63) D1010 H0030 (f ixed)

When the data for each operand are set as above, the following operati on condition is specified.
D1000=4 & D1001=3020 D3020 is specified as the comm and code setting register and D3021 is
specified as the command data setting register.
Data table:
Register Data contents Signal direction
D3020 Command code
D3021 Command data Write
Example operation:
For example, to send the Run f orward command to all the Inverters, set the command code H FA00
into D3020 and the value HC400 into D3021.
For the command code and the command data format, refer to your I nverter manual.
